WebThere are four main stages of mitosis: prophase, metaphase, anaphase, and telophase. The longest stage of mitosis is typically metaphase, which is characterized by the alignment of the chromosomes at the equatorial plane of the cell. During prophase, the first stage of mitosis, the cell's nucleolus disappears and the nuclear envelope breaks down.
